34.14 Slow Clock Mode

The SMC is able to automatically apply a set of “Slow clock mode” read/write waveforms when an internal signal driven by the Power Management Controller is asserted because MCK has been turned to a very slow clock rate (typically 32kHz clock rate). In this mode, the user-programmed waveforms are ignored and the Slow clock mode waveforms are applied. This mode is provided so as to avoid reprogramming the User Interface with appropriate waveforms at a very slow clock rate. When activated, the Slow clock mode is active on all chip selects.
